A new shader test that shows new shading/lightning capabilities. It's in an early development stage but it's giving nice results. You can download it here:

You will see two textures. There's a light circling around the scene. The top texture is the enhanced one. And the bottom one is normal texture. If this demo works on your PC then NBK will work too.

This is what you will see. (Looks better in action :) )
